[0032] The left clamping joint 7541 and the right clamping joint 7542 are the same in structure. Hereinafter, the left clamping joint 7541 is taken as an example for description. The left clamping joint 7541 comprises an upper joint 75411 rotatably connected with the mounting frame 751, a lower joint 75412 rotatably connected with the upper joint 75411, and a clamping hook 75413 connected with the lower joint 75412.

The center rotating shaft 7543 is inserted into the position of the inclined joint rod 754123 to rotatably connect the left clamping joint 7541 and the right clamping joint 7542.
[0033] In this embodiment, the driving rod structure 753 comprises a connecting block 7531 connected with the output shaft of the clamping cylinder 752, and two driving rods 7532 connected with both ends of the connecting block 7531 and respectively connected with the center rotating shaft 7543.
[0034] The automatic quantitative feeding device 7 for die casting equipment in the embodiment of the application is driven downward by the clamping cylinder 752 when in use, at this time, the two driving rods 7532 of the driving rod structure 753 drive the central shaft 7543 to move downward, the central shaft 7543 simultaneously applies downward force to the left clamping joint 7541 and the right clamping joint 7542, since the upper joint 75411 of the left clamping joint 7541 and the right clamping joint 7542 is rotatably arranged at the upper end of the mounting frame 751, the end part of the upper joint 75411 connected to the lower joint 75412 can swing inward, that is, the lower joint 75412 of the left clamping joint 7541 and the right clamping joint 7542 is driven by the lower end part of the upper joint 75411 to move inward, then the lower joint 75412 of the left clamping joint 7541 and the right clamping joint 7542 is rotated around the central shaft 7543, thus, the lower longitudinal joint rod 754122 of the lower joint 75412 of the left clamping joint 7541 and the right clamping joint 7542 is close, that is, the clamping hook 75413 of the left clamping joint 7541 and the right clamping joint 7542 is close, and the raw material is clamped.

The output shaft of the Y-axis servo motor 721 is connected with the Y-axis driving wheel 722. The Y-axis driven wheel 723 is arranged at the other end of the mounting bracket. The Y-axis driving wheel 722 and the Y-axis driven wheel 723 are peripherally arranged with the Y-axis transmission belt 724. At least one Y-axis slide rail 725 is installed on the mounting bracket and extends along the length direction of the Y-axis transmission belt 724. The Y-axis servo motor 721 provides driving force, cooperates with the Y-axis driving wheel 722 and the Y-axis driven wheel 723, and can drive the Y-axis transmission belt 724 to move on the Y-axis.
[0038] Meanwhile, the X-axis moving mechanism 73 comprises an X-axis base plate 731, an X-axis servo motor 732, an X-axis driving wheel 733, an X-axis driven wheel 734, an X-axis transmission belt 735 and an X-axis slide rail 736. The X-axis base plate 731 is slidably connected with the Y-axis slide rail through at least one X-axis sliding block 730. The X-axis servo motor 732 is installed at one end of the X-axis base plate 731 and electrically connected with the PLC controller. The output shaft of the X-axis servo motor 732 is connected with the X-axis driving wheel 733. The X-axis driven wheel 734 is arranged at the other end of the X-axis base plate 731. The X-axis driving wheel 733 and the X-axis driven wheel 734 are peripherally arranged with the X-axis transmission belt 735. At least one X-axis slide rail 736 is installed on the X-axis base plate 731 and extends along the length direction of the X-axis transmission belt 735. The X-axis base plate 731 is connected with the Y-axis transmission belt 724 through an X-axis clamping block 737. The X-axis servo motor 732 provides driving force, cooperates with the X-axis driving wheel 733 and the X-axis driven wheel 734, and can drive the X-axis transmission belt 735 to move on the X-axis.
[0039] Since the X-axis base plate 731 is slidably arranged on the Y-axis slide rail 725 through the X-axis sliding block 730 and connected with the Y-axis transmission belt 724 through the X-axis clamping block 737, the Y-axis moving mechanism 72 can drive the X-axis moving mechanism 73, the Z-axis moving mechanism 74 and the raw material clamping mechanism 75 to move as a whole on the Y-axis.
[0040] Meanwhile, the Z-axis moving mechanism 74 comprises a Z-axis base plate 741, a Z-axis servo cylinder 742 and a Z-axis driving shaft 743. The Z-axis base plate 741 is slidably connected with the X-axis slide rail 736 through at least one Z-axis sliding block 740. The Z-axis servo cylinder 742 is installed on the Z-axis base plate 741 and electrically connected with the PLC controller.

The Z-axis servo cylinder 742 provides driving force and drives the raw material clamping mechanism 75 to move on the Z-axis.
[0041] Since the Z-axis substrate 741 is arranged on the X-axis sliding rail 736 by the Z-axis sliding block 740 and is connected to the X-axis transmission belt 735 by the Z-axis clamping block 744, the Z-axis moving mechanism 74 and the raw material clamping mechanism 75 can be moved in the X-axis direction as a whole by the X-axis moving mechanism 73.
[0042] The automatic quantitative feeding device for die casting equipment can move the raw material clamping mechanism in the X-axis, Y-axis and Z-axis by the X-axis moving mechanism, Y-axis moving mechanism and Z-axis moving mechanism, so that the raw material clamping mechanism can continuously and uniformly feed multiple raw materials into the furnace, realize the purpose of grabbing raw materials at different positions and conveying them into the furnace, and has high efficiency, saves labor and reduces cost. Meanwhile, before the feeding action is performed, the material liquid level in the furnace is sensed in real time by the float ball liquid level meter, the float ball liquid level meter transmits the liquid level information to the PLC controller, and then the PLC controller controls the feeding into the furnace, so that the material liquid level in the furnace is maintained to a set state, effectively avoids the problem of sharp temperature drop due to excessive feeding, ensures the stable temperature of the material in the furnace and improves the quality of the castings.

7. The automatic quantitative feeding device for die-casting equipment according to claim 6, characterized in that, The X-axis moving mechanism includes an X-axis base plate, an X-axis servo motor, an X-axis drive wheel, an X-axis driven wheel, an X-axis transmission belt, and an X-axis slide rail. The X-axis base plate is slidably connected to the Y-axis slide rail via at least one X-axis slider. The X-axis servo motor is mounted on one end of the X-axis base plate and electrically connected to the PLC controller. The output shaft of the X-axis servo motor is connected to the X-axis drive wheel. The X-axis driven wheel is located at the other end of the X-axis base plate. The X-axis transmission belt is arranged around the X-axis drive wheel and the X-axis driven wheel. At least one X-axis slide rail is mounted on the X-axis base plate and extends along the length of the X-axis transmission belt. The X-axis base plate is connected to the Y-axis transmission belt via an X-axis clamp. The X-axis servo motor provides driving force, which, in conjunction with the X-axis drive wheel and the X-axis driven wheel, drives the X-axis transmission belt to move along the X-axis.
8. The automatic quantitative feeding device for die-casting equipment according to claim 7, characterized in that, The Z-axis moving mechanism includes a Z-axis base plate, a Z-axis servo cylinder, and a Z-axis drive shaft. The Z-axis base plate is slidably connected to the X-axis slide rail via at least one Z-axis slider. The Z-axis servo cylinder is mounted on the Z-axis base plate and electrically connected to the PLC controller. The Z-axis drive shaft is connected to the output shaft of the Z-axis servo cylinder and the mounting bracket of the material clamping mechanism, respectively. The Z-axis base plate is connected to the X-axis transmission belt via a Z-axis clamping block. The Z-axis servo cylinder provides driving force to drive the material clamping mechanism to move on the Z-axis.
